Du fragst OrderHistory total falsch ab.

So etwa gehts nämlich, und du machst die Abfrage in der History nur 1 x pro Order:

int LastBuy = 0;
int LastSel = 0;
int History_index = 0;
int LastHistory_index = 0;

bool BuyInv=false;
bool SelInv=false;

for(i=OrdersTotal()-1;i>=0;i--)
{
   if(OrderSelect(i,SELECT_BY_POS))
   {
      if(OrderType()==OP_BUY &&OrderMagicNumber()==Buy_MN &&OrderSymbol()==Symbol()) BuyInv=true;
      if(OrderType()==OP_SELL&&OrderMagicNumber()==Sell_MN&&OrderSymbol()==Symbol()) SelInv=true;
   }
}

History_index = OrdersHistoryTotal();
if (LastHistory_index != History_index)

   {
